WotC and Hasbro co-own the Baldur's Gate IP. Hasbro is WoTC's parent. To separate the two could be an IP disaster. To buy Hasbro it will likely have to be broken up due to competition rules. I can't see what good it would do Larian Studios to be acquired by X.
Though Larian can be argued to be classed as indie, they are their own publisher too. They have had success with the Divinity series, and hit it rich with Baldur’s Gate 3. Larian won’t pursue D&D IP any more, and I think they have now two big and one small game in the works. It is a bit hard to see Swen Vincke team up with Elon Musk.
Musk is now enticing his cohorts with Hasbro bait. Hasbro is more than PC games. It is a lot to put on your shoulders.
I do think that Musk will go ahead with his game studio, but I won't be surprised to see it being Epic like. xAI develops a game engine specialised in AI creation. It is also a marketplace where games, apps, and assets can be sold. Now and then, when a title is liked, xAI will back it, slapping their name on it. It will never be like Valve.
No company will replace Valve, anyone who thinks they can deconstruct it is doing a disservice to consumerism.
As it is, the loudest dev that sings praise to Musk's plan is not the most ethical and best practised person. The vibe is strange.
Now and then, on X, Musk and John Cormack share thoughts. I like Cormack, and he is leaning strong towards AI or, well, AGI. Though I can't see Cormack saddle up with Musk. Cormack is in a strong position to do his own things.
